I normally have a hard time finding ALS-XZ, but this time I found one which is also a pattern technique called a vwxyz-wing. Ib terms of the ALS-XZ Rule the two ALS's are 1, 2, 3, 8, 9 in row 8 with cells marked with ', and 2,3 in r9c5. The restricted common digit X is 2 and the common digit Z is 3. The digit 3 in r8c4 sees all the 3's in the both ALS's cells and can be eliminated. In terms of the rhe vwxyz-wing V is 2 and Z is 3. If r9c5 is 2 then r8c2589 is a locked set and 3 cannot be in r8c4. If r9c5 is 3 then again 3 cannot be in r8c4.

Just as every naked set has an equivalent hidden set that makes the same deduction, it is also the case that every ALS will have an equivalent AHS that makes the same deduction. A relatively large ALS implies a relatively small AHS which may be easier to see, especially if you use coloring.

From the hidden point of view, not only are there fewer digits in this case, but you have your coloring to aid you. It is simple from coloring to note that 4's and 7's are locked in r8c134. One other digit that is almost locked in those cells is 2. Thus we have...

(4&7&2)r8c134 = (2)r8c5 - (2=3)r9c5 => r8c4 <> 3

In this case one can break the hidden triple down into a greater amount of smaller hidden sets like...

(4&7)r8c14 = (7-2)r8c3 = (2)r8c45 - (2=3)r9c5 => r8c4 <> 3

...or using the locked sevens AH-pair instead of the locked fours AH-pair...
